Charles S Peirce "Theory of Signs"
Wolfgang Weingart "frozen music" - we spoke about Wolfgang Weingart in respect to this book
and here is an article
Seems that Weingart emerged after the Swiss movement of Neue Grafik, because swiss typography needed a "fresh impulse." He broke down rigid concepts and introduced many different typographical relationships: slant, weight, size, readability, etc. He is credited as the "father" of "New Wave" typography...sounds pretty cool to me
O and I found an even better article

Deconstructivism (I guess versus Constuctivism....interesting!)
